'IO ALL WHOM IT MAY CONOERN:

Be it;kno\vn that I, M. H. POPE, of Susquehanna Depot, in the county ofSusquehanna, and State of Pennsylvania, have invented a' new andimproved IIay -Harpoon; and I do hereby declare that the following is affull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specication.

The drawing represents a central'section of my improved hay-fork.

The invention consists in construction ot' certain parts of thehay-fork, which willhereafter be fully set forth. i

The shank A is provided with the tines et a, pivoted thereto at Z1,which tines are thrust out horizontally from the shank and case B,through the slots it' in the latter, when the said shank is pushed down.

A slotted arm, L, is .pivoted to the cap E at e, and the bifurcations ofthis arm pass down by the shank when the latter is to 4he'locked ineither of the two positions which the notches m and n permit.

'A Iever,f, having a ring, Z, and shoulders,'c, is pivoted to the cap atg; and, when the forked arm t is pressed down horizontally, the levelfis raised vertically, which brings the reduced part below the shouldersof said lever into the slot of the arm 7L, and the shoulders c passabove the slotted arm, as shown, thus holding the shank rmly,tfor thebottom of the slot in the arm bears against the side of the shank, andactuates the notch m to catch upon the edge of the hole through whichthe shank passes.

The same operation is required when the shank is thrust down, and thetine's are to be locked in a hori- Azontal position, suitablefor liftinghay. When the hay is to be discharged from the tines, the tripping-line,attached to the ring of the leverf, is drawn, which-liberates the armIt, and the notch n, being slightly bevelling or rounding, will slipfrom tbe edge ofthe cap, and permit the case to slip downward, thusdrawing in the tines.

1 The pointed head D is screwed into the case, as shown, and, being aseparate attachment, enables the case to be made at less cost than whenthe point is a continuous part of the same.

` The point is also readily detachable, vfor the purpose of removing thehay-seed, dirt, and other foreignsubstances that may get into the case.

I claim as new, and desire to secure by Letters Patent- The slotted arm7L, leverf, both pivoted to the cap E of the case B of a hay-harpoon,al1 substantially as shown and described, and for the purpose set forth.

MJ H. POPE.
